1. Field of the Invention
The present invention relates to a waterproof cover, and more particularly to a waterproof cover for protecting an audio system from water.
2. Description of Related Art
In outdoor activities, an audio system including items such as a loudspeaker, a CD player or a radio for reproducing music is a requirement. However, the audio system has a control panel that will often be affected by water in some situations such as boats, leisure spas etc. Therefore, the audio system generally has a waterproof cover mounted in front of the control panel.
A conventional waterproof cover has an inner gasket, a frame, an outer gasket and a shield.
The inner gasket is mounted at a first side of the frame and has a first opening defined therethrough. The frame has a second opening defined therethrough and corresponding to the first opening.
The outer gasket is mounted at a second side of the frame. The shield has a tongue protruded from a rear side thereof. Two lugs are formed at two ends of the tongue and positioned in the apertures respectively. Therefore, the shield is pivotally mounted on the frame.
In use, the waterproof cover is mounted in front of the control panel of the audio system. Blocked by the inner gasket and the outer gasket, water cannot dampen the control panel, and the audio system is protected.
However, limited by the manufacturing technology, the shield, the outer gasket and the frame can not be tightly assembled together, and gaps exist between the shield and the outer gasket and between the outer gasket and the frame, so water can penetrate the gaps, and the audio system may be seriously damaged by the water.
Therefore, the invention provides a waterproof cover to mitigate or obviate the aforementioned problems.
The main objective of the present invention is to provide a waterproof cover for an audio system that is waterproof to completely prevent water from dampening the audio system.
Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
With reference to
The shield (10) has two extensions (11) oppositely extending out of the shield (10) and respectively having holes (111) defined in a free end of the extension (11).
The gasket (20) has a configuration the same as that of the shield (10) and is securely attached to an inner side of the shield (10). Especially, the gasket (20) is able to form a waterproof padding on an outer peripheral edge of the shield (10).
The frame (30) can be installed in front of a control panel of an audio system including items such as a loudspeaker, a CD player or a radio (not shown). An opening (300) is defined through the frame (30) and two arcuate faces (31) are respectively formed on two lateral sides of the frame (30). Two positioning legs (32) protrude from a rear face of the frame (30), and each positioning leg (32) has a pivot seat (33) formed on an outer side of each of the positioning legs (32). Two arms (34) are provided to pivotally connect each one of the positioning legs (32) to the shield (10).
The recovery force adjusting assembly (40) includes adjusting holes (41) and two springs (42). Each spring (42) connects one positioning leg (32) to one arm (34) so that when the arm (34) is pivoted relative to the frame (30), the spring (42) is able to provide a recovery force to pull the arm (34) back to a closed position.
With reference to
With the springs (42), the arms (34) and the shield (10) are able to pivot relative to the frame (30). With reference to
With reference to
With reference to
From the above description, the concept of this invention is simple and thus the entire structure is easy and compact. However, the waterproof effect is far better than any of the conventional waterproof covers on the market.
Furthermore, to prevent excessive pivotal movement of the shield (10) relative to the frame (30), a stop (343) is formed on an inner side of each of the arms (34), and the pivot seat (33) has a pivot space (332) defined by two limiting plates (331) formed in the pivot seat (33). Therefore, the stop (343) always moves inside the pivot space (332) and the shield (10) and the frame (30) is protected.
Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only. Changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
